# 模拟程序说明文档
#### （一）、框架结构说明
config：存放项目配置文件
dada：存放项目需要的数据和产生的数据
doc：项目帮助文档，markdown格式编写
img：存放项目需要的图片资源
lib：车机协议实现的类，以及各种业务逻辑
log：项目运行日志文件
static：存放网页端图形操作界面的静态文件，包含：js，css，图片等
templates：存放网页模板文件 html
views：存放网页端操作的后台处理逻辑，以及页面的展示逻辑
run.py：启动项目图形操作界面主程序，访问：127.0.0.1:5000 即可
requirements.txt：设置项目需要的依赖库
### （二）、文档目录
[1、lib使用库说明](doc/lib_details.md)
[2、如何使用web图形操作界面](https://www.baidu.com/)
### （三）、图形界面展示
#### m500操作界面：
![alt text](doc/img/m500_1.png "Title Text")
#### 车安优操作界面：
